140 Chapter 7
Controlling the OBR Remotely
Response: Returns a number indicating the x-axis units used to define
the Integration (or Sensing) Area. The possible responses
are:
0 :
nanoseconds
1 :
meters
2 :
feet
3 :
inches
4 :
millimeters
Example:
CONF:XUNI?
Response:
1
CONF:INTW?
Response: 1.5
The
CONF:XUNI? response
of 1 means that x-axis units are
meters (See
āCONFigure:XaxisUNIts?ā
on page 139). This
means that the CONF:INTW? response should be
interpreted as 1.5 meters, and that any CONF:INTW,
CONF:INTS, or CONF:INTC commands should specify
their units in meters.
CONFigure:RATE
Usage: CONF:RATE
{sweepRate}
Description: Sets the laser sweep rate in nm/sec, allowing for Fast Scan
Mode. The default sweep rate is set by the device EEPROM
and is usually 10 nm/sec. The rate can be set as high as 200
nm/sec. If the user-specified sweepRate is higher or lower
than allowed, CONF:RATE will set the sweep rate to the
closest possible value. The CONF:RATE? query can be
used to retrieve the actual rate that was set. Higher sweep
rates allow faster measurements,
but
higher sweep rates
may
result in less
accurate measurements
for a device with a high
return loss.
Response:
None
Example: CONF:RATE
100
This command sets the laser sweep rate to 100 nm/sec.
